The invention discloses an auxiliary air inlet type cooler in the field of material processing devices. The auxiliary air inlet type cooler comprises a cooling box body fixedly arranged on a rack; the bottom end of the box body is connected with a collection hopper; the top end of the box body is provided with a feeding hole connected with a feeding air seal machine; the upper end of the box body is provided with an exhaust inlet, and the lower end of the box body is provided with an air inlet; the box body is internally provided with a secondary air inlet device; the secondary air inlet device comprises two main air inlet pipes and a plurality of branch air inlet pipes fixedly arranged on the main air inlet pipes; the main air inlet pipes are vertical to the branch air inlet pipes; the main air inlet pipes are communicated with the branch air inlet pipes; the main air inlet pipes are provided with four air inlets in total; and the air inlets on the main air inlet pipes and the air inlet on the box body are connected with an air blower arranged at the outer part of the box body. Through installing the secondary air inlet device inside the box body, the air input is not reduced, meanwhile, the cooling time is prolonged, and the cooling effect is ensured; in addition, the auxiliary air inlet type cooler is simple in structure, low in cost and capable of being used for cooling and drying particle materials.
Description
technical field [0001] The invention relates to a material processing device, in particular to a cooler. Background technique [0002] Pellet feed cooler is the main equipment for cooling and dehumidifying the hot and wet pellet feed after pelleting and drying. The pellet feed just pressed out of the pellet machine has a temperature of about 60-90°C and a moisture content of about 10. % ~ 18%. Such pellet feeds are soft, easily broken and deteriorated. They must be dried and cooled to reduce the moisture content of the finished product to 10% to 14%, and the temperature to close to room temperature (generally no more than 3 to 5°C) before they can be packaged. Transport and safe storage. [0003] In the prior art, using a cooler to cool down and dehumidify the pellet feed is the simplest and cheapest method. Its main working principle is: use air as the cooling medium, and the temperature and relative humidity of the air will change accordingly after entering the cooler. ...
